ABSTRACT:
A tape reel, comprising a hub and a pair of flanges attached one each to the opposite ends of the hub and obtainable by integrally molding one of the pair of flanges at the end of the hub and separately molding the other flange and subsequently fastening the separately molded flange by ultrasonic welding to the free end of the hub, is provided either on the hub or on the separately molded flange with means for absorbing impacts of the ultrasonic vibrations and, thereby, is prevented from sustaining fractures and distortions during the work of ultrasonic welding.
